Hi,
I have couple of doubts


* How do you find "json" has module named "tool" ?.


* Why dir(json) not showing "tool" ??

>>> import json
>>> dir(json)
['JSONDecoder', 'JSONEncoder', '__all__', '__author__', '__builtins__',
'__doc__', '__file__', '__name__', '__package__', '__path__',
'__version__', '_default_decoder', '_default_encoder', 'decoder', 'dump',
'dumps', 'encoder', 'load', 'loads', 'scanner']
>>>


* How to list all modules of a package in python console ?.


* Is this what you guys are using to check modules of a package ?.

ls /usr/lib/python2.7/json/ | grep .py$
decoder.py
encoder.py
__init__.py
scanner.py
tool.py
